Solving:

ax + b = cx + d# # # #

We must get the variables together before solving!!

5w + 1 = 2w + 13

Examples:1. x + 50 = 2x + 100

2. 9n + 5 = 4n – 35

3. 3(2x + 4) = 2(2x + 25)

4. 12y + -9(y + 5) = 8(y – 1) – 2 + 2y

5. 3m – (5m – 2) = 4m + 2(m – 7)

A concert was held at RHS. The income from the concert came from a $250 donation from the school and ticket sales at $8 per ticket. Rent for the auditorium was $200. The school had to pay the band $1400, plus $2 for each ticket sold. The school broke even (didn’t make or lose any $).

How many tickets were sold?
